Limited clinical trials using an innovative new device to monitor brain chemistry on a second-by-second basis are underway to answer that life-and-death question, according to an article in the current issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine. Brain injury is the leading cause of death and disability worldwide.
C&EN Senior Editor Celia Henry Arnaud describes a phenomenon called depolarization, in which brain activity decreases in patients following initial trauma. The condition involves a wave of chemical changes that spread from the site of injury and inactivate nerve cells.
Since reactivation of these cells requires large amounts of glucose, monitoring glucose levels in a patient's brain can help doctors tell whether or not a patient is taking a turn for the worse. The article points out that a promising new device could provide a faster and more useful way to monitor brain glucose than current methods, which are inefficient.
Now in development at Imperial College London, the new so-called "microfluidic method" measures glucose quickly and continuously — in fractions of a second instead of hourly.
The device is currently being tested in patients who have suffered trauma, stroke, or aneurysm (a balloon-like enlargement of a brain artery). In the future, the device could be used in patients with milder forms of brain injury and used in a way that is less invasive, the article notes.ARTICLE FOR IMMEDIATE RELEASE

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
